Long time no post. I need to get my own computer fixed so I can make consistent progress.

Anyway, here's the masher.

What I did:
-put in more in between shades for the upper body (perhaps too many)
-adjusted the eye (no eye lid this time)
-adjusted shading on the fins, teeth, and body
-I got the idea of how the tail will work now I got to make it look decent

What I haven't done:
-make the fins larger on the "mouth open" frame
-something else I m. I'm just too tired to remember right now

I will upload the finished frames tomorrow, but you should still post your critiques. I'm also working toward finishing this tomorrow.

After working on the masher I realized there seems to be a difference in the shading styles between the two. I think the Buzzer may need more needs more in between shading on the back-end, but I thought I'd ask first the community first.

Edit: It does still look a little puffy around the edges and I didn't get the shading right on the furthest right cone, but I can't stand to look at it anymore today. Also, looks like a gradient in-game. I don't know how I feel about that.

This is about as close to a triangle as I think I can get while keeping the grooves indented and the size close to the original sprite. I still notice inconsitantcy between the top and bottom because I realized something.

I ripped the drill sprites myself and they match up perfectly to the one I've been using. This drill still doesn't look sharp because it's going along a "perfect" triangle. I still believe the only way to make it look more pointy is to have the top (right) of each section angled inward slightly like in the sprite (though better than my first attempt, of course).

Considering the colors that the masher is going to be up against, I don't think the darker shade is really necessary. Also, I think you should make the eye round. And I wouldn't worry about having too many shades, like I said, It appears to be meant to have color shifting paint, I'm surprised it could be done with manual shades.

About the Eggman, His waistline appears to be based off a section of a circle, like the original, but the new one's circle is too small, making it look like you're seeing him from a lower point of view than the original.
